    Measuring and Analyzing Liquidity and Volatility Dynamics in the Euro-Area Government Bond Market
    (World Scientific Publishing, 2019-07-12) ;
    This chapter examines the impact the European sovereign debt market crisis had on liquidity and volatility dynamics and their interdependencies in the eurozone government bond market. In particular, we examine the impact across different countries and across different maturity buckets within individual countries. A comprehensive high-frequency dataset from MTS, Europe's premier electronic fixed-income trading market, is employed to construct a variety of microstructure liquidity and volatility measures. We analyze important trends in these measures over both tranquil and crisis periods. Additionally, we study time-varying correlations as well as the intertemporal interactions of liquidity proxies with volatility and returns. Our findings provide useful insights to regulators and policy makers on the relative strengths and weaknesses of domestic and global financial systems.

    A comment on 'Cross-border merger, vertical structure, and spatial competition'
    The aim of this paper is to revise and correct the results obtained in Beladi et al. [Beladi, H., Chakrabarti, A., Marjit, S., 2010. Cross-border merger, vertical structure, and spatial competition. Economics Letters 109, 112-114]. Specifically, we prove that the Nash equilibrium locations of the downstream firms are the same in the pre-merger free-trade case as they are following a cross-border upstream merger.

    Simulating financial contagion dynamics in random interbank networks
    The purpose of this study is to assess the resilience of financial systems to exogenous shocks using techniques drawn from the theory of complex networks. We investigate by means of Monte Carlo simulations the fragility of several network topologies using a simple default model of contagion applied on interbank networks of varying sizes. We trigger a series of banking crises by exogenously failing each bank in the system and observe the propagation mechanisms that take effect within the system under different scenarios. Finally, we add to the existing literature by analyzing the interplay of several crucial drivers of interbank contagion, such as network topology, leverage, interconnectedness, heterogeneity and homogeneity across bank sizes and interbank exposures.

    Sovereign bond return prediction with realized higher moments
    This paper analyzes whether realized higher moments are able to predict out-of-sample sovereign bond returns using high-frequency data from the European bond market. We study bond return predictability over tranquil and crisis periods and across core and periphery markets at the index and country level. We provide fresh evidence that realized kurtosis is the dominant predictor of subsequent returns among higher moments and other predictors such as CDS spreads, short-term interest rates and implied stock market volatility. Our findings further underline that sovereign bond return predictability is stronger during crisis periods and more pronounced for bonds of lower credit ratings.

    Addendum to Eleftheriou and Michelacakis (2016)
    Following the publication of Eleftheriou and Michelacakis (2016a), it was brought to our attention that the problem identified and corrected in Eleftheriou and Michelacakis (2016a) affects more papers than just the Beladi et al. (2008). Two such instances of published papers that we know of are the Beladi et al. (2010a) and Beladi et al. (2010b). The aim of this short addendum is to warn the reader against the validity of the results in these two papers and perhaps others using the same basic duopoly model as in Beladi et al. (2008). We look into the origins of the fallacy and make an announcement of corrected versions of some of the affected conclusions referring elsewhere for precise details.

    On the term structure of liquidity in the European sovereign bond market
    The paper provides a high-frequency analysis of liquidity dynamics in the eurozone sovereign bond market over tranquil and crisis periods. We study time series of liquidity across the yield curve using high-frequency data from MTS, one of Europe’s leading electronic fixed-income trading platforms. We document flight-to-liquidity effects as investors prefer to trade on shorter-term benchmarks during liquidity dry-ups. We provide evidence of significant commonalities in spread and depth liquidity proxies which are weaker during the crisis period for both core and periphery economies although periphery countries display higher commonality than core countries during the crisis. We show that illiquidity of the periphery countries plays an important role in market dynamics and Granger causes illiquidity, volatility, returns, and CDS spreads across the maturity spectrum in both calm and crisis periods. Liquidity is priced both as a characteristic and as a risk factor even when controlling for credit risk, pointing to liquidity’s systematic dimension and importance.
